title: Hyperglobulinemic purpura in the course of multiple myeloma.
abstract: Secondary hyperglobulinemic purpura of Waldenström is characterized by polyclonal gammopathy associated mainly with autoimmune diseases. Its occurrence with multiple myeloma is very rare. We described a patient who developed characteristic lesions of hyperglobulinemic purpura in the course of IgA myeloma. Skin biopsy revealed deposition of IgA in the blood vessels.
